Describe the bug
A control query computes a strategy for eventually reaching a certain location, but the same location is not eventually reached under the strategy.
Also SMC queries get stuck in an urgent location complaining that exponential rate and invariant are not specified.

To Reproduce
Steps to reproduce the behavior:

  1. Consider the following one-process model:
    image
  2. Go to Verifier
  3. Check E<> P.Good that P.good is reachable
  4. Check strategy C = control: A<> P.Good is successful, observe popup "Synthesized non-deterministic strategy" (expect "Synthesized deterministic strategy").
  5. Check A<> P.Good under C and observe that it is not satisfied (expect to be satisfied).
  6. Check simulate[<=1000]{ P.location } under C and observe error message "Unspecified delay due to missing invariant and exponential rate on line 1 of Project/P/Move: P.Move" (expect no error message as Move location is urgent, which is equivalent to c<=0 invariant).

Version(s) of UPPAAL tested
At least UPPAAL 5.0.0 and 5.1.0-beta5 are affected

Additional context
The model is attached: control-strategy-bug.zip
